Abstract: 523,531. Ticketissuing. FISHBURN, J. E., and WEBB, C. F. Dec. 5, 1938, No. 28731. [Class 106 (iii)] In a ticket printing and issuing machine the ticket is first printed while forming part of a continuous strip with a portion of the matter to be printed thereon, the ticket being subsequently severed from the strip and after such severing being printed with the remaining matter. The machine includes a printing head 10 having a pair of number printing devices on each side of its axis and also a printing stereo, a counter and a dating device. The depression of a starting key causes a member 50 to be rotated thus advancing the ticket strip 39 into the grip of head 10 and a roller 58. The head rotates printing the ticket with two serial numbers and the stereo matter and further advancing the strip. A severing knife 53 is then operated by cam and linkage action from member 50 and the severed ticket is then engaged by the dating device, which prints the remaining matter and ejects the ticket from the machine. The printing surfaces are inked by a roller 65 mounted on a swinging arm which receives ink from a fixed roller 69.

Abstract: 1303719 Recording/playback apparatus SONY CORP 4 Nov 1970 [4 Nov 1969] 52464/70 Heading G5R A tape recorder mode selection switch is biased such that whenever the tape slackens the switch automatically reverts to the STOP mode. In the arrangement shown, a cam 244 is fixed to the shaft 42 of a mode selection switch (16, Fig. 1, not shown), and is continually urged by a roller 266 mounted on a spring-biased lever 268 to a STOP position where the roller 266 engages a concave portion 264 of the cam, amd also where a further roller 286 of a latching mechanism 246 engages a deep cam recess 250. The latching mechanism will however maintain the arrangement in an operating mode position, as shown, with roller 266 not at 264 and with roller 286 engaged in a shallow cam recess 252, by applying an opposing force greater than the return-to-stop force applied by roller 266. This is achieved through the use of a cocked lever 280, the lever being primed by a spring 298 when the lever 278 supporting roller 286 is rotated on rotation of cam 244 for mode selection; the lever 280 is prevented from rotation, by a tab 310 on a lever 304, as long as the tape is taut and the lever 304 is in the full-line position. If however the tape slackens, lever 304 moves to the dotted line position, lever 280 rotates clockwise, spring 298 is de-energized, and roller 266 forces the cam to rotate to the STOP position.

The voltages are provided by a 3-phase supply of V. < 0, V. < 120 and V. < 240; a sustain voltage of #3 V. is the sum of any two which are 120 degrees out of phase. Zero voltage is obtained by changing the applied voltages on both electrodes of a selected element to V. < 240; half selected elements still receive a voltage of #3 V. The voltages may be sinusoidal or square wave. Alternatively voltages of-V < 0 and V. < 60 and zero can be used. In another embodiment voltages V 1  and V 2  of frequencies f 1 , f 2  are used.
